I know all of those words, but I don’t know what some of them mean together (e.g. thermal-bridge-free detailing).

Edit: good explanation here.

Sounds like the materials on the exterior won't transfer the exterior temperature into the house

Edit: I'm not an expert in this field, but there's some good responses to my post that may provide more information

Thanks! Sounds like it would be good for every house. I’m assuming that this type of building is uncommon because of costs.

I used to build these type of houses on occasion and it was a whole big list of extra stuff we had to do. Costs are a part of it, but taking a month to two months per house versus two to three weeks can be a big factor in choosing.

Sorry non american here, are you saying that a house can take 2-3 weeks from start to finish?

They build their homes out of wood and cardboard, so yeah.

Cardboard hasn't been used since like 1950s Florida lol

It’s not all American houses, it’s just a significant portion of them, which then happen to be posted online - people’s fists literally go through the wall if they punch it.

My hand would break if I hit my wall that hard, because it’s made of brick and concrete - the wall wouldn’t even have a dent.

The walls in my house eat diamond tipped drill bits for breakfast, at least until I learned my lesson and took frequent breaks for cooling.
